No bullet hole decals on props. DL included for compiling

[Sathor]

Sadly, my custom props never feature bullet hole decals!
Kit helped me today and tested. He does not get bullet hole decals on my props either. So I need your help to find the error. The qc is standard ...

$modelname sath_props\sath_trashcan02.mdl
$cdmaterials sath_materials\props\

$scale 1

$body studio "sath_trashcan02_ref.smd"

$staticprop

$surfaceprop "metal"

$sequence idle "sath_trashcan02_still" loop fps 1

$collisionmodel "sath_trashcan02_phys.smd"
{
$Mass 10
$concave
}

The collision model is very slightly bigger (0.1 units in most dimensions) than the body model. So I guess it is either the exporting or the compiling. I hope anybody can help - by downloading the files below.
It includes the three SMDs, the qc, the texture files and a test map. If someone would compile the prop himself and test it in the test map and tell me whether he or she will get bullet decals, I'd be very happy.
